Measurement method of the error of signal amplitute for ultrasonic flaw detector 超声探伤信号幅度误差测量方法
Measurement method of the error of signal amplitute for eddy current flaw detector 涡流探伤信号幅度误差测量方法
During the exaltation of output signal swing , the adoption of the resistance connecting across can reduce the output resistance 在提高输出信号幅度的同时,采用跨接电阻的方式减少输出阻抗。
In voice transmission , to compress the signal amplitude into a narrow range be cause the amplifiers are linear over wide ranges 在话音通信中,因放大器的线性范围有限,把信号幅度压缩到一个较小范围的处理。
Abstract this paper investigated the window effects and the spectrum amplitude errors in hamming windowing spectrum analysis in detail and gave its compensation coefficients 摘要主要以汉明窗为例,定量分析了窗函数引起的信号幅度谱误差,给出了相对幅度谱补偿系数的理论值。
